The New York Tunnel Extension of the Pennsylvania
Railroad diverges from the New York Division in the
Town of Harrison, N. J., and, ascending on a 0.5%
grade, crosses over the tracks of the New York Division
and the main line of the Delaware, Lackawanna and
Western Railroad. Thence it continues, with light
undulating grades, across the Hackensack Meadows to
a point just east of the Northern Railroad of New Jersey
and the New York, Susquehanna and Western Railroad,
where it descends to the tunnels under Bergen Hill
and the North River. (Plate XVI.)

That portion of the line lying west of the portals
of the Bergen Hill Tunnels has been divided into two
sections: First, the most westerly, known as
the Harrison Transfer Station and Yard (Plate XVII),
which is located on the southern side of the New York
Division, Pennsylvania Railroad, and extends from
the connection with the New York Division tracks at
grade up to the point of crossing the same, where the
Pennsylvania Tunnel and Terminal Railroad has its beginning;
second, the Meadows Division of the Pennsylvania Tunnel
and Terminal Railroad, which is a double-track railroad,
5.08 miles long, extending from a point just west
of the bridge over the New York Division to a point
300 ft. west of the western portals of the Bergen
Hill Tunnels.

Harrison Transfer Station and Yard.—­The
necessities for the Harrison improvements are two-fold:
First, as a place to change motive power from steam
to electric, and vice versa; second, as a transfer
for passengers from trains destined to the new Station
at Seventh Avenue and 33d Street, New York City, to
steam or rapid transit trains destined to the present
Jersey City Station, or to the lower part of New York
City via the Hudson and Manhattan Tunnels,
and vice versa.

All steam trains from Philadelphia, the South, and
the West, from New Jersey seashore resorts, and local
trains on the New York Division bound for the new
Pennsylvania Station, will change their motive power
from steam to electric engines at the Harrison Transfer
Station. Likewise, all trains from the Tunnel
Line will change from electric to steam motive power
there, and passengers coming from Jersey City and the
southern section of New York City can take through
trains at the Harrison Transfer platforms. It
is estimated that the time required to make this change
of motive power, or to transfer passengers, will not
exceed 3-1/2 min.
